Preheat your oven to 200°C (390°F) and line a baking sheet with parchment paper. This ensures even roasting and easy cleanup.
While the oven heats, cut the pressed tofu into 2 cm cubes, making sure they are uniform for even cooking.
In a small bowl, whisk together soy sauce, chili paste, minced garlic, sesame oil, and the juice of half a lime to create a vibrant marinade.
Gently toss the tofu cubes in the marinade, ensuring all pieces are well coated on every side. Let sit for at least 30 minutes to absorb the flavors.
Arrange the marinated tofu cubes on the prepared baking sheet in a single layer, giving each piece space to crisp up.
Bake in the oven for 25-30 minutes, flipping the tofu halfway through to promote even browning and crispiness. The tofu should turn deep golden and develop a crackly exterior.
Once done, remove the tofu from the oven and let it rest for 5 minutes. This helps the texture to set and makes it easier to serve.
Squeeze the remaining half of the lime over the roasted tofu for a fresh, zesty finish, and serve hot with your favorite sides or as a snack.
